discharge In the example shown, the lower end 9 of each supporting member is normallyfpre vented from making-any rising'm'ovement and also from making any lateral movement by being mounted in a divided box. The body H, while the top K is attached to the body of the box by means offaturned down latch K In order to raise the spindles G it is suflicient to turn the latchdown into the position indicated in dot and dash lines in Fig. The top K isthen raised by means of a collar g on the foot of the supporting member, while the box body K remains at tached to the'stay H. j It isalso to be noted. that the stay H, while being capable of pivoting witlithe gun carriage on the platformgD, is connected to thej latter by mea ys of the cap 7L carrying the bearingblock It is to be observed, when the gun is mounted in firing position, that thestay HQ constitutes abufierplate that-is normally maintained separated; from but in close juxtaposition to the platform D' by; the elast c device I, and. that the weight of the carr age withits load is carried onthe stay or buffer plateby the supporting member G connected to the carriage and mounted on the stay O1 -Plflt e..{ During firing, the-shock'from a Y is vimparted; through the carriage and supporting member Gr to the buffer plate or stay H, and the initial energy of the shock is absorbed by the elastic device I; The elastic device, yields to this strain and sidual energy of the shock, where it'is further absorbed or transmitted to the ground. There is comparatively little play, as at J,

between the bufi'er'plate' and the platform. and as a result but little movement of the gun and carriage is required to accommodate the reco l. "Gonsequently, as the gun has been displaced but comparatively llttle,

it returns almost instantly to its original .ction constitutedsimply by the elastic tires I firing position and with little Or noinipaifment of its aim. I u w r l In .h'e .exa nple of Figs. 5 to 8, the supporting 'members' servingto transmit the firing strains to the wheel platform-.D, are carried by the axle-B. 1 The interposed elastic device which normallykeeps the lower ends of the supporting "members at a. distance J off'the platfornris in this construcof'the wheelsC bearing upona lateral border D of the fplatforrn D; .lThe amount of' play J may be adjusted when the parts are at rest. For this purpose'each supporting member may, "shown in Fig. 6, con

sist of-a socketwG carried-:byfthe axleB and having. a screw-threaded bore in which the screw-threaded part of a supporting mem- K of this box is fixed to the stay tering ofthe gun carriage upon the platform "readily understood that theyielding of the elastic tires 1, during the'firing, will rapidly bring the feet of the supporting members into contact with the platform D;

In this example of construction the cen;

. the axle B. The fixingof the socket in the position of use and position for transport (indicated in dot and dash lines in Fig. 5) respectively; is effected by'meansof aysuitablecatch; The trail A may be provided with two hooks or catches a a for engag ing a cut-away axlepin G carried. by the socket G p In the example of Figs; 9t0 11, a single supporting member G is provided in the formof a screw spindle? arranged in the plane of the longitudinal axis of the gun carriage in such a manner that its: axis coincides withthe axis of the wheel platform D. It is inov aloly mounted in a nut-like support 9 pivoted on an axle-like stay A connectlng the-cheeks of the gun carriage A.

The wheels C, which are kept at a 'constant distance from the axis of the platform by the body. of the said platform, bear upon a border D as in the precedingexample. The elastic device that normally assures the play J between the foot of the support- 11;; member and the platform is in this con struction constituted by springs I bearing at one end upon'the axleB and at their other 'ends against the underside of abutments formed on the cheeks of the gun carriage.

Infirmg at hlgh angles of elevatlon the yielding of thespr'ings Iallows the foot of the supporting member to come into contact with the platform D.

The nut-like support G and the body G of the supporting member may be made capa- *ble of being raised together for transport into the position indicated in dot and dash llnes n Fig. 9.1.The nut-like support is for this purpose provided with vcut-away axlepins G one of which may look the supportfing member to a hook a of the gun'carriage so asqtohold it in its position of use. The

other cut away axle-pin may'lockthe sup porting member'inposition; for transport to another hook a carriedby the gun carriage.
